“…Phase equilibria of the Mn‐Ho binary system were studied experimentally, [41,47] and were calculated by Wang et al., [49] Kim et al., [20] and Wang et al [24] . According to the reported experimental data and calculations, five Mn‐RE (RE = La, Nd, Gd, Dy, and Ho) binary systems were reassessed in our group [21–24] . The calculated results are consistent well with the experimental data.…”

“…indicated that the results of the invariant reactions determined by Kirchmayr and Lugscheider [34] in the Mn‐Tb binary system are unreliable after comparing with the reported phase equilibria of the Mn‐Nd, Mn‐Gd, and Mn‐Dy binary systems. Furthermore, phase equilibria of the Mn‐RE (RE = Nd, Gd, Dy, and Ho) binary systems were studied experimentally in our previous work, [22–24] which shows that the invariant reactions in the Mn‐Tb binary system observed by Kirchmayr and Lugscheider [34] are not available. Okamoto [63] reviewed the Mn‐Tb binary system.…”

In this work, eight Mn‐RE (RE = Ce, Pr, Sm, Tb, Er, Tm, Lu, and Y) binary systems were reassessed thermodynamically by the CALPHAD method based on the reported optimizations and experimental information. Self‐consistent thermodynamic parameters to describe Gibbs energies of various phases in eight Mn‐RE binary systems were obtained. The calculated phase equilibria and thermodynamic properties of eight Mn‐RE binary systems are in good accordance with the experimental results. Furthermore, phase equilibria and thermodynamic properties of 13 Mn‐RE (RE = La, Ce, Pr, Nd, Sm, Gd, Tb, Dy, Ho, Er, Tm, Lu, and Y) binary systems were discussed systematically in combination with the present calculations and the reported optimizations. A trend was found for the variation of phase equilibria and thermodynamic properties of the Mn‐RE binary systems. In general, as the RE atomic number increases, the enthalpies of mixing of liquid alloys as well as the enthalpies of formation of the intermetallic compounds become increasingly negative, and the formation temperatures of the intermetallic compounds become higher. The results provide a complete set of self‐consistent thermodynamic parameters for the Mn‐RE binary systems, and a thermodynamic database of 13 Mn‐RE binary systems was finally achieved.
